Advantages vs 3.2V LiFePO4 Batteries

Higher Nominal Voltage: 3.7V lithium polymer provides higher working voltage than 3.2V LiFePO4, delivering stronger power output and better performance in small electronics.
Higher Energy Density in Same Size: Traditional 3.7V li-polymer offers higher capacity and energy density in the same dimensions, supporting longer runtime for compact devices.
Wider Application in Consumer Electronics: Matches the charging and discharging logic of most small smart devices, with better compatibility and simpler circuit design.
More Mature Mass Production: Stable supply chain, lower cost, and higher consistency for mass production compared to LiFePO4 polymer in small-capacity sizes.
Better Low-Temperature Performance: Performs more stably in cold environments than most 3.2V LiFePO4 batteries, making it suitable for outdoor and portable devices.

Application

Laser pointers, Mountain bike taillights, Other small lighting devices, Bluetooth headsets, Smart bracelets, Mini speakers, and other wearable and portable electronic products, Dashcams, Portable auxiliary lights
